Which tool is usually used to drive a lag screw?

The tool typically used to drive a lag screw is the socket wrench. Lag screws, also known as lag bolts, are heavy-duty fasteners designed for fastening wood and other materials. They feature a hexagonal head, which allows them to be driven in using a wrench. A socket wrench is suited for this purpose because it can securely grip the head of the lag screw, allowing for the necessary torque to be applied for installation.

Using the socket wrench facilitates the process of driving in lag screws more efficiently compared to other tools, which may not provide the same level of grip or leverage. For instance, a hammer is not suitable for driving a lag screw, as it may not provide the precision required and could damage the fastener. An open-end wrench and pliers also lack the appropriate design to effectively turn the screw while maintaining sufficient grip and torque.
